JTAG to access the internal NOR flash?
-
I've got JTAG to work with the board, but i can only control the CPU but not the internal flash. I tried compiling a uboot image that can be run from RAM, but did not have much luck with that. Has anyone used JTAG with onion before?

Probably, this gentleman can be of help:

Wonder how onion does uboot development. Do they directly access the NOR flash ?
